Hydnopora question

[chandigz]

Only if mine touched something did you ever see sweepers(1 1/2"+). And man could they ever cause damage.

[reeferious]

my 8 inch square fluorescent hydno never hurt anything as nearest thing is 1 inch away from it. i find that if other corals ie: monti, poci, most acros. birdsnest etc that dont send out sweepers can live almost within touching distance of hydnos.
